Oh, wow. Those blue valves are basically what you've ordered. They're not installed in that position from the factory.

 

Hmmmmm..... well that's.......interesting? Concerning?

I'm wondering if I'd be better off getting a good aftermarket regulator valve/filter and just pulling out everything from the pump output to the tank bulkhead. It would require a bit more engineering on my end, but might serve me better long term. I've had symptoms as early as 2021 (mainly just emission system codes, and nothing that impacted performance until 2024).

 

it's possible the previous owner had fuel system issues and a dealer already installed the fuel line kit. Now that you've got the tank open you can check everything over. Be thankful you have a Volante. I still have scars (physical and emotional) from my experience with the coupe.
